The specified value of the index parameter is less than zero or greater than the item count.

If the DrawMode property is not set to DrawMode.OwnerDrawVariable, the value of the index parameter is ignored because all items in a standard ListBox are the same size. You can use this property when you are using an owner-drawn ListBox to determine the size of any item within the ListBox.
